For most limbs an normal IK will do but for limbs like dog's and horses they have to work a little different.

This is because in human arms/legs the IK would end at the writs/ankle but as the done structure is different in some other animals the IK needs to finish at the Metacarpals.

This is because those animals look like they have a "backwards knee" but intact that's actually there wrist joint and its the Metacarpals that are on the ground.

To make this work a different IK set-up is needed, so for this im using the spring IK. This ik is quite similar but it handles more that one bend better (e.g. the knee and wrist).
